data

[Adam F. <ad...@da...>]

I got PHP Weather running very quickly without any problem.  But I have 
no idea how to access the information as variables.  Here's what the 
documentation provided.
<?
$metar = get_metar('KIND');   // Indianapolis, IN  - my home
$data = process_metar($metar);
$temp = $data['temp_f'];
?>

so I attempted to loop through the $data array and echo out the values, 
surprisingly no values came out what-so-ever.  using the pretty 
function, that returned absolutely nothing as well.  I read through 
the .inc files hoping to find something there.  And I can do it, but it 
would probably take me a full day of staring at it to acquire the list 
that I'm looking for.  What I would like to have is:
temp in farenheit
temp in celsius
clouds - (party cloudy, clear skies, etc.)
visibility (in km and miles)
etc, etc, etc,  the more info I could have the better.

I spent several hours trying to find documentation to tell me this.  
But couldn't come up with anything.  Any help would be very much 
appreciated.

Try using print_r() on the result of a call to process_metar():

echo "<pre>\n";
print_r(process_metar(get_metar('EKAH')));
echo "</pre>\n";

You can also look for '$decoded_metar[' in phpweather.inc.

Does the above code work? If so, then it's very strange if you say
that the $data array is empty...

Did you use print_r() on $data?

You're looking for the lines that store values in the $decoded_metar
array.

Entry 'temp_f',

Entry 'temp_c',

That's a bit tricky as there can be several cloud-layers (up to
three). But look for 'cloud_layer1_coverage' or
'cloud_layer1_condition' for the first layer.

> visibility (in km and miles)

Entries 'visibility_miles' and 'visibility_km',

Yes, there isn't any documentation for this (except the source :-).

You should also take a look at the code found in CVS:

Individual files with diffs etc:

  http://cvs.sf.net/cgi-bin/viewcvs.cgi/phpweather/phpweather/

Snapshots:

  http://phpweather.sourceforge.net/downloads/

That code requires PHP version 4 and uses objects, but the decoding
works much like the code you've seen. The advantage is that the array
is documented, see this message:
